baxi 105e no HW unless CH is running

[grumpy]

hi. I am having a problem with the hot water on my 105e, I can get pipng DHW as long as i have the CH running but none when CH is off. which makes me think it must be a flow switch thats not sensing that i am asking for HW,can anyone tell me if I am on the right track please??.
if so can anyone tell me what parts I might need to fix it.??

CHeck the diverter is moving fully and operating the microswitch and that the mswitch is switching cleanly.

That's the diaphragm kit. If the HW is really good, DV's likely to be moving properly - hence suggest looking hard at the microswitch.
